VEHICLE-BRAKE.

SPECIFICATION forming part of Letters I Application 510a August 9,1899.

- To all ,whomit Hwy concern:

Be it known that we, RICHARD C. .G; NEU MANN and GEORGE L..HAR' 1'MANN, of Seattle, in the county of King and Stateof Washing tpn, have invented a new and Improved Vehicle-Brake, of which the following is'a full,

' clear, and exact 'descriptiolL p I I One object of the invention, is to-provide a "simple and effective vehicle-brake of that IO type which in application contacts with the ground and raises the rear wheels from elf the ground. A further obj videa brake of the charactersp'ecified that mayhe nsedduring all se'asonsof theyear hand. in the construction of which but few parts are used andall parts willbe light and durable and to furnish brake for wheels having rubber tires and to preventunnecessarywwear of'thesame. e

The invention consists in thenovel: construetion and-combination of the several '.parts,"as will: be hereinafter fullygset forth,

and pointediout in the claims. 7 Reference is to-be had to the accompanying 'drawir g.,,=for ninga part ofthis specification, is

v in which similar characters'of reference indicate corresponding parts in all the-figures.

Figure 1 is a vertical section through the 3.0 t cle, illustrating the application of-the. im-

proved brake thereto, the brake beingin op-' erative'jposition. Fig. 2 isa View similar to v "Fig..-1;.the' supporting-wheel being omitted 35 and the brake being-illustrated in an'upper position or out of engagement; with the "ground. Figl 3 is a partial rear elevation of the running-gear shown in Fig. 1 and one of the brakes applied thereto; andFig; 4'isa perspective view of a'brake-shoe viewed from 'the'bottom, which shoe is particularly adapt ed for use in'winter.

The reaclLA, the axle l-grand wheel of the vehicle maybe of any suitable construction. Two brake-shoes D are employed, both of -which are adapted for engage nentwith the ground, and these brake-shoes are located between the rear wheels and adjacent to the inner faces thereof. Th brake-shoe shown in Fi si' Til and 3 is that which is ect of the invention is to prorear portion of the running-gear of the vehi Patent Normans, as my 1, iced, SerialNc. 726.677. on iii-Dane ordinarily usedin summer or when 'ice and" .snoware notes the ground, andsaid brakee slide is provided with a central fiat surface and upturned ends, and when the shoe is for summer hs'e the under face of said shoe is '55 smooth; The said shoe is preferably pro- "vided-at each side ofitsc'ent'er with'up- -wardly-extending cars 10, which ears are either attached directly to the shoe or Ito'the side-pOrtionsof a'plate 11, extending longitne 6e dinally of the upper portion of the shoeat its center and boltedthereto.

ciall'y adapted for use in winter,-in which it will beg'observcd that the straight-bottom surface 65 Ivided with a'hanger Efand this hanger is 70 made in two sections 13 and'lhconneeted attheir centers bya'rnle-joint 15, fiexing'in direction of the front of thevehicle, and the" "lower member 13 of each brake-shoe hanger E is pivotally attached :at its lowerlend to a 7 brake-shoe D, between the. ears of said shoe, while theupper end ofthe upper me nber 14 pffeach'brake-shoe hanger is pivotally attached to a clip 16, se.cured to the axle 'BL forward of-the brake-shoehangers E, and said" rock-'shaftll is journaled in suitable bee "r .ings '18 attached, to the upper portion "of the "running-gear by bracketsli) or their equivalents. Two arms 20 are secured to the said. 8 5

rock-shaft 17, one'opposite the forward edge of. each brake-shoe hanger E. ,These arms 20- serveas levers and at their rear ends-are pivotally connected with turnhuckles 21', which turnbuckles receive the forward ends '90 of lift-rods. 22, and said lift-rods at their rear ends are provided with forks 23, mounted upon the pivot-pin of the rule-joints of the said brake-shoe hangers EL When the leverarms arein the horizontal position shown in Fig. 1, the sections of the brake-shoe hangers are perpendicular and in horizontal alincmcnt and the brake-shoes Dare forced 1 upon the ground, raising the rear wheels of the vehicle from olf the ground; but when In Fig. it-we have illustrated a'shoe espek Arock-shaft 17 is located below, the reach, 80

gagement with the ground. The shaft 17 is rocked by attaching thereto alever 24, which extends downwardly and connecting a brakebar' 25 with the said lever 24, which brake'-t bar maybe-connectedwith a hand-lever or foot-lever within easy reach of the driverior' ilevc'r', worked by other power;

' Abra'ce 26 is pivotally attached to thecen Itral'ouiter' 'portion of each brake shoe 1), an'd each-brace 26- atits upper end is connected ,withga turnbnckle' 27, and said turnbnckles -'27 are pivotally mounted "on theends of the rockshaft 17. HThefhrake-shoes are further supported "by means of intermediate braces 28, wh ich are pivotally attachedto the inner central portions of the brake-shoes D; and the intermediate brace-rods 28 are connected at their upper ends with'turnbuck-les 29; These turnbuokles 29 are pivotally attached to op posite ends of a clip;30-, said clip being piv-' ot'a'lly located on the rock-shaft 17 The forward-ends of the brake-shoes are preferably. connected :bychains 31' or their equivalents with the lower portions of the intermediate hraces28 vIt will be observed that the liftrods 22 have an adjustable connection with the lift levers or arms 20 andtheir all the braces have an adjustable: connection with the rock-shatt 17, so that the device is readily a the rock-shaft,intermediate braces piv'otally .8 5 L applicable to any forrn of vehicle.

Having thus described our invention, we claim as new and desire to secure by Letters lB ate| 1t-. I n j l. ;A vehicle-brake-coinprisinga brake-shoe adapted for engagement'with the ground,'a rock-shaft mounted in the vehicle, changer constructed in hinged sections, one of which is connected to said brake-shoe, and a-connection between said rock shaft andfsaid hanger whereby when the shaft is rocked the sections 95 the ha will be moved t6 bend or straighten the hanger, as set'forth; I

2. A vehicle-brake consisting of brake-shoes adapted for engagement with the ground,

hangers for the brake-shoes constructed in hinged 'sections," a rock-shaft, lift=levers carried by the 1 rock-shaft, lift-rods connecting said lift-levers with the brake-hangers at the hinges thereof 'and means for rocking the g .said shaft, for the purpose described.
